Also check the insulation between these two connections.
If the connections are faulty, carry out the following checks:
Check the insulation, continuity and absence of interference resistance between:
Computer connector track 6 Track 32 on the intermediate
connector
Computer connector track 17 Track 31 on the intermediate
connector
Also check the insulation between these two connections.
Check the insulation, continuity and absence of interference resistance between:
Sensor connector one of the
2 tracksTrack 31 on the intermediate
connector
Sensor connector the other track Track 32 on the intermediate
connector
Also check the insulation between these two connections.
If all the checks are in order, contact Techline.
1.DEFNOTESNone
Visually inspect the condition of the target and sensor (for dirt, metallic contamination, bearing grease, etc.), and
clean using compressed air if necessary.
If there is a lot of grease on the target, contact the Techline.
Check that the wheel speed sensor mounting is in good condition.
Check the sensor/target air gap over one wheel revolution: 0.1 mm < Rear wheel gap < 1.2 mm.
Check the conformity of the target (condition, number of teeth = 48) using the specific command SC001 Check
target teeth.
If the checks are correct:
–the computer fault memory has been cleared,
–exit fault finding mode, switch off the ignition and carry out a road test.
–Replace the rear left-hand "disc-hub-bearing" assembly (see MR364 or MR370 Mechanical, 33A, Rear axle
components, Bearing: Removal - Refitting) if the fault reappears.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

The voltage displayed in the parameter (PR005) is the + after ignition feed voltage of
the computer and not the hydraulic unit power feed.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present following a road test at a speed of > 36 mph (60 km/h).
Check the connections and the condition of the battery terminals.
Check the condition and position of the ABS fuses in the engine fuse and relay box.
Check the 50A power fuse in position 5 on the power fuse board.
Check the 25A fuse F13 on the UPC and the correct locking of the grey 4-track PPHI connector (Vdiag 44) or
test the 25A fuse F8 on the UPC and the correct locking of the black 6-track CM connector (Vdiag 48).
Check the connection and condition of the tab 1 red wire of the grey connector.
Check the connections on the 26-track connector of the ABS computer.
Check the ABS earths on tracks 1 and 4 (attached under the ABS unit) and carry out an inspection of the entire
ABS wiring.
Check the continuity between the fuses and tracks 2 and 3 of the computer connector (+ Before ignition present
on the tracks) and between the UCH and track 18 of the computer (+ After ignition present on the track).
Clear the computer fault memory. Switch off the ignition.
Switch on the ignition again and carry out another check using the diagnostic tool.
If the fault is still present, contact the Techline.

TACHOMETRIC INDEX PROGRAMMING
NOTESSpecial notes:
ABS warning light flashing at 8 Hz outside fault finding conditions.
The BOSCH ABS 8.0 computer supplies the vehicle speed signal to all vehicle systems that use this information
(instrument panel, engine management, etc.).
This vehicle speed signal replaces the one supplied by the speed sensor located on the gearbox. The ABS
computer calculates the vehicle speed from the speed of the wheels and the circumference of the tyres fitted on
the vehicle.
Note:
The vehicle speed is sent by wire (track 23) to the xenon bulb computer, radio and electric sunroof, and via the
multiplex network to the other computers.
The tyre circumference must be programmed into the memory of a new computer. This consists of
entering a number X using the VP007 "Tachometric index" command on the diagnostic tool.
Once the index has been entered using the VP007 command, clear the computer fault memory and then switch
off the ignition.
Use the parameter PR030 to check that the index entered has been stored correctly.
If the fault is still present, contact the Techline.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
